Shane is one of 3 large chain schools in Taiwan. They have branches in virtually every neighborhood of the island. The idea is that kids of all ages come straight from school to their after school program, which means they usually open up within a block or two of each school. There are benefits to working for a large school, but you should know what you're getting into.
I remember that my boss once told me she was calling the head office to "Order a new teacher," sort of the way you might order a sweater from gap.com. This is really the mentality they have towards teachers in general. They bring in an enormous amount of foreigners each year, mostly who have no teaching experience, BA's in unrelated fields and marginal cultural sensitivities. They have developed a curriculum that any white faced monkey could teach. The students do learn and make progress, though not at a speed that I was comfortable with.
The job is not hard, once you get a feel for it. It will take more out of you than sitting in an office, but it's pretty fair to expect to start your work day after lunch and end only shortly after dinner. You'll be making less in your first year than the average salary, but remember that if you're taking this job, you probably have absolutely no teaching experience. If you do, you may be making a relatively comparable salary. You'll never make **big bucks** of other teaching jobs, but you'll be plenty comfortable and rarely stressed. The job leaves you with enough time and money to enjoy Taiwan, learn Chinese, get into trouble, make friends or do whatever you please.
Shane certainly has it's problems. Most of them go with the territory of a large operation. You should know what you're getting into before hand. Much to their credit, they spell out exactly what you'll be doing and how you'll be paid in the contract, no more no less. This puts them a big step above other schools. I taught there for one year and then moved on. It was probably the best year of my life. I learned an enormous amount, I had a great deal of fun and grew up a great deal. I often complained about Shane while I worked there, then I took a much higher paying job with an extremely disrespectful boss at a mismanaged school that never paid me what they promised.
Shane is what it is: it sets a low bar which it meets every time. I'm sure there are better schools out there, but I learned the hard way that there are also far worse.
